因素分析作为经济学(及其他科学)中的一种研究方法,是立足于推论待研究的指标和形成该指标的各因素之间是否存在确定性的相关关系。这种相关关系可以记作表意明白的两个或两个以上变量的函数式。相关关系的特征取决于待研究现象的本质和性质,而他们的具体表达式则取决于经济理论。经济——数学模型可以根据待研究指数的性质和相关关系的理论概念用逻辑运算的方法或用概率论与数理统计学的方法(如相关分析和回归分析)及其各种变通的方法来研制。
Factor analysis, as a research method in economics (and other sciences), is based on deciding whether there is a definite correlation between the indicators to be studied and the factors that form the index. This correlation can be written as a functional expression of two or more variables that are consciously understood. The characteristics of the relationship depend on the nature and nature of the phenomenon to be studied, and their concrete expression depends on economic theory. Economic-mathematical models can be based on the theoretical concepts of the nature of the index to be studied and the theoretical concepts of correlations, using logical methods or methods of probability and mathematical statistics (such as correlation analysis and regression analysis) and their various alternative methods. .
